[Accumulation of 111In-antimyosin antibody at the focal site of inflammation].
An p6-year-old man with anterior acute myocardial infarction was administered antimyosin antibody labeled with 74 MBq (2 mCi) 111In, and abnormal hot activity was observed in the left lung by immunoscintigraphy. 67Ga-citrate scintigraphy also showed abnormal uptake in this lesion. At this time, this patient complained of fever and cough with sputum, and roentgenography showed a coin lesion-like shadow at the same location of the lung. By treatment with antibiotics, his symptom was improved and coin lesion-like shadow disappeared. So we thought the RI uptake area in the left lung was inflammatory lesion. This case suggests that 111In-antimyosin antibody can be trapped to the focal site of inflammation.
